A meme is any bit of information that can spread from one human mind to another. Memes, Dawkins pointed out, share many of the traits of genes. They can reproduce by copying themselves from one mind to another. As you read this book, memes that have entered my brain are being copied into your brain. They undergo a form of natural selection, with some memes dying out and some flourishing. And memes, like genes, can be mutated, or combine with others to produce new variety. Pg. 7
